This book still sticks out as one of Paizo's biggest missteps. It was extremely rushed and it shows.
At least half of the new classes don't even need to exist as anything other than archetypes. Even among the ones that actually work, most feel very uninspired.
There are a few good things in it, but not really enough to justify buying it. It's not worth your money and it's best not to encourage sloppy work.
Hopefully Paizo learns from this and prioritizes quality over quantity and speed from now on.
